screen_height_px (int) – Screen height in pixels
screen_width_cm (float) – Screen width in centimeters
screen_height_cm (float) – Screen height in centimeters
distance_cm (float) – Eye-to-screen distance in centimeters
origin (str) – Specifies the screen location of the origin of the pixel coordinate system.
sampling_rate (float) – Sampling rate in Hz

Methods

`__init__`(screen_width_px, screen_height_px, ...)	Initializes Experiment.
`pos2vel`(arr[, method])	Compute velocity time series from 2-dimensional position time series.
